It works as,

1. The OUT pin is a low level when there is no object between the photoelectric sensor, and the red LED is lit.
2. The OUT pin is a high level when there is an object between the photoelectric sensor, and the green LED is not bright.
3. The OUT port can be connected to MCU directly, Than MCU can calculate how many circles the smaller car has run per unit

Note: The sensitivity is not adjustable.
